<p>O estudo foi realizado no município de Rio Acima, localizado ao sul da região metropolitana de Belo Horizonte - MG. Na primeira etapa, foi feita a determinação das áreas de preservação permanente (APPs) do município, segundo a Lei 12.651 e a resolução CONAMA 303/2002 (esta última para delimitar as APPs de topo de morro), utilizando cinco bases topográficas distintas: vetorização de cartas do IBGE na escala de 1:50.000, imagem SRTM, Topodata, ASTER V2 e uma base vetorial disponibilizada pelo Codemig com curvas de nível equidistantes em 10 metros. Na segunda etapa, foram calculadas as áreas de cada uma das classes de APP resultantes dos mapeamentos feitos a partir de todas as bases e, em seguida, estes valores foram comparados. Ao final, foi observado que os resultados obtidos a partir da base do IBGE e da imagem ASTER V2 são os que apresentam característica mais restritiva, ou seja, com maiores áreas de preservação. Por outro lado, o mapa de áreas de preservação permanente confeccionado a partir da imagem SRTM foi o que apresentou caráter menos restritivo. Neste estudo também são discutidas outras diferenças entre os mapas elaborados a partir das cinco bases. </p><p> </p><p><strong>Palavras–chave:</strong> Município de Rio Acima, áreas de preservação permanente, modelos digitais de elevação, resolução espacial.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong>Abstract </strong></p><p>This study was conducted in the municipality of Rio Acima (Minas Gerais State) located in the southern Belo Horizonte metropolitan region. In the first stage five different topographic bases were used to lay down the city permanent preservation areas (PPA) according to the Law 12,651 and CONAMA resolution 303/2002 (the latter to delimit the hilltop’s PPAs PPAs). These bases are the following: the vector at a 1:50.000 scale provided by the Brazilian Institute of Geography and Statistics (IBGE), SRTM image, image provided by INPE Topodata project, ASTER V2 Image and a vector base released by Codemig with 10 meters contour distance. In the second stage the areas of each one PPA classes were calculated resulting from all mapping bases. Then these values were compared. Finally it was observed that the results obtained from the ASTER V2 image and IBGE base are those with more restrictive features or in other words the result with lager PPAs. Moreover, the map of permanent preservation areas made from SRTM image showed the least restrictive character. This study also discusses other differences between the maps drawn from the five bases.</p><p><strong> </strong></p><p><strong>Keywords</strong>: Rio Acima municipality, permanent preservation areas, digital elevation models,   spacial resolution.</p>

O objetivo do trabalho é analisar, de uma perspectiva geral e comparativa, o comportamento das lideranças políticas dos municípios pertencentes à Região Metropolitana de Belo Horizonte frente aos constrangimentos e incentivos às relações intergovernamentais, no âmbito metropolitano, proporcionados por três diferentes modelos de organização da cooperação intergovernamental: (a) aquele imposto pelo governo federal nos anos 1970, altamente hierarquizado; (b) o do “hipermunicipalismo simétrico”, instituído após a Constituição Estadual de Minas Gerais, de 1989; e (c) o de integração dita “negociada”, que está sendo implantado desde 2006. Objetiva-se analisar as estratégias adotadas pelos municípios da RMBH diante dos distintos graus de liberdade que lhes foram concedidos pelos três modelos, e da capacidade de monopolização da agenda e de priorização de determinados interesses por parte dos municípios do eixo econômico e dos governos estadual e federal.Palavras-chave: metrópoles; gestão metropolitana; relações intergovernamentais; Região metropolitana de Belo Horizonte; Ambel. Abstract: The paper aims to analyze, from a general and comparative perspective, the behavior of the political leadership of the municipalities that are part of Metropolitan Region of Belo Horizonte, Brazil, given the incentives and constraints to the intergovernmental relations, in the metropolitan sphere, posed by the three distinct models institutionalized to produce intergovernmental cooperation: (a) the one imposed by the Federal Government in the 1970s, highly hierarchical; (b) the one characterized by “symmetrical hipermunicipalism”, that was institutionalized after Minas Gerais State Constitution of 1989; and (c) the one of “negotiated integration”, which has been built since 2006. The objective is to analyze the strategies adopted by the municipalities in the face of the several degrees of autonomy conceded by the three models and of the capacity to monopolize the agenda and to give priority to certain interests by the municipalities belonging to the region’s economic axis and by state and federal government.

Title in Portuguese: Deliberação online em consultas públicas? O caso da assembleia legislativa de Minas GeraisAbstract: This paper utilizes deliberative democratic theory to analyze an online public consultation forum about political reform implemented by Minas Gerais State Legislature (ALMG), Brazil. Six topics guided the discussion of the 752 posts from this forum: (1) inclusiveness; (2) provisions of reasons; (3) reciprocity; (4) mutual respect; (5) orientation as it relates to the common good; and (6) articulation between arenas. The results point to (1) an over-representation of male participants and of dwellers of the Metropolitan Region of Belo Horizonte, although no participant monopolized the discussion; (2) the prevalence of on topic posts that present some form of justification for positions advocated; (3) very low levels of reciprocity between posts and of interactivity markers; (4) extremely high levels of respect; (5) different forms of articulating the common good; and (6) low impact in decision-making but interesting connections with the broader public sphere, specially through a story published by a newspaper.The findings of this study indicate a low probability of internal dialogue, which is contrary to the outcome desired by the supporters of deliberation. However, the potential for deliberative debates still exist if broader lenses are adopted. Tabulations between variables suggest that people tend to provide more reasons when commenting on more controversial discussions, although they tend to be less reciprocal in these situations. Thus, the hypothesis that suggests a preference for participation in conversations among like-minded discussants is supported by the analyzed data.Resumo: Este artigo busca analisar uma consulta pública online sobre reforma política promovida em 2011 pela Assembleia Legislativa de Minas Gerais. Embasado pela teoria deliberacionista, o estudo de 752 posts guiou-se pela discussão de seis tópicos: (1) inclusividade; (2) provimento de razões; (3) reciprocidade; (4) respeito mútuo; (5) orientação para o bem comum; e (6) articulação entre arenas. Os resultados indicam: (1) uma sobrerepresentação de participantes masculinos e oriundos da Região Metropolitana de Belo Horizonte, embora não tenha havido concentração de posts em alguns comentadores; (2) o predomínio de posts on topic e que apresentam justificativas para as posições advogadas; (3) índices muito baixos de reciprocidade entre posts e de uso de marcadores de interatividade; (4) graus muito elevados de respeito; (5) diferentes formas de ligação das justificativas a ideias de bem comum; (6) o baixo impacto decisório e a conexão com outras arenas da esfera pública, destacando-se a relação com uma matéria publicada em jornal de grande circulação. Os achados são ambivalentes para os defensores da deliberação, indicando baixa probabilidade de deliberação interna ao fórum, mas algum potencial deliberativo quando se adotam lentes mais amplas. Os cruzamentos entre variáveis sugerem que as pessoas tendem a prover mais justificativas em discussões mais controversas, embora tendam a dialogar menos nesses casos. Assim, a hipótese da preferência por conversas entre like-minded encontra respaldo nos dados analisados.

ABSTRACT The Montreal Battery of Evaluation of Amusia (MBEA) is a battery of tests that assesses six music processing components: scale, contour, interval, rhythm, metric, and music memory. The present study sought to verify the psychometric characteristics of the MBEA in a sample of 150 adolescents aged 14-18 years in the city of Belo Horizonte, Minas Gerais, Brazil, and to develop specific norms for this population. We used statistical procedures that explored the dimensional structure of the MBEA and its items, evaluating their adequacy from empirical data, verifying their reliability, and providing evidence of validity. The results for the difficult levels for each test indicated a trend toward higher scores, corroborating previous studies. From the analysis of the criterion groups, almost all of the items were considered discriminatory. The global score of the MBEA was shown to be valid and reliable (r K-R20=0.896) for assessing the musical ability of normal teenagers. Based on the analysis of the items, we proposed a short version of the MBEA. Further studies with larger samples and amusic individuals are necessary to provide evidence of the validity of the MBEA in the Brazilian milieu. The present study brings to the Brazilian context a tool for diagnosing deficits in musical skills and will serve as a basis for comparisons with single case studies and studies of populations with specific neuropsychological syndromes.

This study was conducted in a probabilistic sam- ple of 2,055 elderly in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil, to examine components of social network (conjugal status and visits by the children, other relatives, and friends) and social support (satisfaction with personal relations and having persons on whom to rely) associated with limitations in performing basic activities of daily living (ADL). Multivariate analysis used the Hurdle model. Performance of ADL showed independent and statistically significant associations with social network (fewer meetings with friends and not having children) and personal support (dissatisfaction/indifference towards personal relations). These associations remained after adjusting for social and demographic characteristics, health status, and other indicators of social relations. Our results emphasize the need for greater attention to social network and social support for elderly with functional limitations and those with weak social networks and social support.

SUMMARY To evaluate soil contamination by parasites in different developmental stages in public squares used as recreation and leisure areas for children in Belo Horizonte (MG, Brazil), 210 soil samples and 141 canine fecal samples were collected from 42 squares in the city. These samples were analyzed by the Caldwell and Caldwell technique and the Hoffman, Pons, and Janer technique. Of the samples analyzed, 89 (42.4%) soil samples and 104 (73.5%) fecal samples were contaminated with Ancylostoma sp., Toxocara sp., Trichuris sp., or Dipylidium sp. eggs; Giardia sp. cysts; or Isospora sp. oocysts. The commonest parasite was Ancylostoma sp., found in 85% soil and 99% fecal samples, followed by Toxocara sp., found in 43.7% soil and 30.7% fecal samples.

The objective of this study was to perform a malacological assessment at the Ibirité reservoir watershed in the metropolitan region of Belo Horizonte (Minas Gerais) and to evaluate the natural infestation rate of Biomphalaria straminea (Gastropoda: Planorbidae)by Schistosoma mansoni (Platyhelminthes: Trematoda) and Chaetogaster limnaei (Oligochaeta: Naididae). The samples were collected from July to August 2002. The B. straminea individuals collected were kept in the laboratory; the natural infestation rate by S. mansoni and C. limnaei was assessed weekly. The malacological assessment identified fivemollusk species present in the Ibirité reservoir watershed: B. straminea, Physa marmorata, Lymnea sp., Melanoides tuberculatus,and Pomacea austrum. Laboratory observations showed that the B. straminea individuals were infected by C. limnaei rather than S. mansoni. Although there was no infection of B. straminea by S. mansoni,presence of B. straminea in itself merits close attention due to possible risk of human schistosomiasis by the local population.

Abstract: The aim of this study was to investigate changes in the frequency of binge drinking and associated factors in the city of Belo Horizonte, Minas Gerais State, Brazil. The sample consisted of 436 adolescents. Data collection involved the Alcohol Use Disorders Identification Test and the Alcohol, Smoking and Substance Involvement Screening Test. Ordinal logistic regression was used in the multivariate analysis. An increase in the frequency of binge drinking was found among adolescents who lived in areas of greater social vulnerability (OR = 1.64; 95%CI: 1.01-2.68), those whose mothers consumed alcoholic beverages (OR = 1.75; 95%CI: 1.05-2.92), those whose fathers consumed alcoholic beverages (OR = 2.02; 95%CI: 1.11-3.68), those with an increased risk of tobacco use (OR = 2.82; 95%CI: 1.07-7.42) and those who attended religious services (OR = 2.10; 95%CI: 1.30-3.38). Knowledge regarding factors associated with a change in the frequency of binge drinking among adolescents can assist in the establishment of public policies directed at health promotion and the prevention of adverse health conditions.
